- Madara had a mentor figure growing up (referred to as his shishou) who is the one who taught him many techniques he knows. His mentor may be much older than him, since he remarks they threw out their back.
|Character||Madara's Nickname||Nickname for them|
Both Madara's parents are members of the Shinkai religious group that worships Kanata as a god, and, as consequence, both the police and society's underbelly act as the Shinkai household's servants.
- In the past, Madara described his relationship with his parents as poor, as he was, in his own words, a "problem child" among the religious group his parents so ardently revered.
- Madara used to rely on his parents’ connections to fly around the world for jobs. Now that he’s at least partially disowned, he stays in Starmony dorms and takes jobs under his own name. One of his screen dialogues has him saying that it is unbecoming to keep depending on his parents for jobs, and that is why he has to work harder to build up connections of his own.
She is a member of the underbelly of society; Kaoru speculates she is an ex-yakuza member.
In Submarine, we learn that Chiaki has spoken with Madara’s mother in a bookshop before, and invited her to rest in his home when her legs were tired. She gave Chiaki a secure communication line which cannot be hacked.
He is a policeman.
She is a shut-in (a hikkikomori) who is sensitive and introverted, and Madara does not speak highly of her. She has a chronic illness. Madara and his sister also had a strained relationship as children, as Madara promised he would fix her illness but failed to do so, and, based on how Madara speaks about her in Beasts, it is possible their strained relationship continues to this day.
In A Dark Night’s Passing, Madara worries that she will have to take over his ‘role’ in the family, which will kill her, and he hopes to regain that ‘role’ one day.
In Submarine, we learn that she has communicated with Chiaki on tokusatsu message boards, sometimes asking about how Madara is doing. She prefers the villain characters to the monster characters.
